Galactic winds enable the exchange of matter between galaxies and their surroundings. In this way, they limit the growth of galaxies, that is, their star formation rate.

The École Polytechnique engineering school, the French national scientific research center CNRS and Safran Electronics & Defense have signed a partnership agreement for a joint laboratory dedicated to the research and development of electric satellite thrusters. The new unit is called COMHET (laboratoire Commun pour l'étude des Hall Effect Thrusters) and will focus on improving HET technology.

A team led by CNRS scientists 1  has discovered that, just like humans, Guinea baboons develop complex strategies to select partners for cooperation, basing their decisions on past interactions.

As social animals, humans communicate with and influence each other by leaving digital traces on the Internet, particularly by using star rating systems on collaborative platforms.

Pulsars, small, very dense dead stars, emit electromagnetic radiation in the form of beams that sweep through space at regular intervals, rather like cosmic lighthouses.

For the third year running, the CNRS is rewarding men and women who share scientific information and knowledge beyond the laboratory walls.

Scientists have discovered fossil evidence of a cyclical climate on Mars, with wet and dry seasons like those on Earth.

In the spring, Alpine glaciers sometimes don a sheer red or orangish veil. Known as 'red snow' or 'blood snow', this phenomenon is caused by the blooming of Sanguina nivaloides , a microscopic alga.

The largest floating ice shelves in the polar ice sheet have lost more than a third of their volume since 1978.

Before modern humans settled definitively in Europe, other human populations left Africa for Europe beginning approximately 60,000 years ago, albeit without settling for the long term.

The mystery of the Mona Lisa lies not so much in her smile as in the painting techniques used by Leonardo da Vinci. Artist, engineer and architect, da Vinci was also an experimental chemist, with the Mona Lisa being his veritable laboratory.

Thanks to the latest catalog from ESA's Gaia satellite, an international team, led by astronomers from Observatoire de Paris - PSL and CNRS, obtains the most accurate measurement of the Milky Way's mass. The subject of an article published in the journal Astronomy and Astrophysics on September 27, 2023, this study opens the way to important questions in cosmology, particularly on the relative amount of dark matter contained in our Galaxy.

Polysiloxanes, the scientific name for silicones, possess exceptional properties, and are used in numerous fields ranging from cosmetics to aerospace.

Imagine a volcanic island about the size of France and over 20,000 metres high. Such a landscape may once have existed on the planet Mars.
